RADIATOR WATER-GAGE.

Application filed March 3, 1919.

To all whom it may concern.-

Be it known that we, ll 11.1mm ll. Gunner and LAUD 0. Guns, citizens oi? the United States, residing at Modesto, county of Stanislaus, in the State of California, have invented certain new and useful Improvements in tadiator lVater-G ages, of which the following is a specification.

This invention is a gage particularly use :tul tor gaging the amount of water in an automobile radiator.

The object of the invention is to provide an adjustable water gage for automobile radiators, and like usages, which may be applied to any size and style of radiator and at the same time provides a strong and. rigid construction which is durable and ellicient.

The invention resides in the sundry details of construction, combination and arrangement of parts hereinafter set forth.

The invention is illustrated in the accompanying drawings which form a part of this specification and the appended claims.

Referring to the drawing:

Figure 1 is a front elevation of the gage.

Fig. 2 is a side elevation of the gage.

Fig. 3 is a cross section oil the gage on line 3-3 of Fig. 2.

Fig. 4- is a front elevation of an automobile radiator and the gage applied thereto.

In the drawings, 1 indicates glass tube inclosed by a tubular metal casing 2 provided with a longitudinal slot 3. The lower end of said casing and tube are mounted in a bracket 4 while the upper portion of said casing andtube are mounted in a bracket 5. A. cup 6 closes the upper end of the tube 1 and casing .2, but is provided with a small air vent to permit escape of the air which be comes trapped in the tube. A nipple 7 is connected to the lower end o'l? tube 1. A threaded rod 8 screws through the bracket land a bracket 9 is secured to the lower end or? said rod in which is screwed a, fitting .10 formed with a nipple 11 on its upper end and with a nipple 12 and a drain conduit 13 on its lower end, a drain cock 14L being screwed into the lower end oi. said drain conduit.

T he brackets 4;, and. 9 are provided with screw openings 15 through which screws 16 are inserted and screwed into the front of an automobile radiator 20 to support the gage on the radiator, the bracket 9 being adjustable with relation to the bracket 4: to fit Specification of Letters Patent.

radiators of different sizes. A flexible tube 21 fits at its ends on nipples 7 and 11 and connects the tube 1 with the fitting 10. A tube 22, preferably of copper or lead is titted at one end on nipple 12 and at its other end on the nipple of a cook 23 leading from the bottom of the automobile radiator through which cock and the tube 22, fitting 1.0, tube 2.1. and nipple 7, water from the radiator is admitted into the gage tube 1 until it reaches the level of the water in the radiator. A red ball 25 floats on top of the water in the tube 1 for indicating the level of the water in the radiator, said ball being visible through the slot 3 of tube 2 and the glass tube 1.

It will be seen that the construction as above set forth provides a gage which may be adjusted to fit any size of radiator and to extend the full length of the radiator. The parts oi the gage are rigidly connected together to prevent rattling and wear which is caused by loose parts and connections. The flexible tube 21 may be provided of such. length as will be necessary for the largest type of radiator, and the purchaser will only be required to cut the tube to the desired length after he has properly adjusted the gage for the size of radiator on which it is to be used.

The foregoing fully describes the invention, however, it is to be understood that certain changes may be made in the construction, combination and arrangement of parts which fall within the legitimate scope of the appended claims.

Having described our invention, we claim as new:

1. An adjustable radiator gage comprising a pair oi bracket members rigidly and adiustably connected together, one of said brackets having a gage tube secured thereto and the other of said brackets carrying a connertion-fitting adapted to be connected to the lower portion of a radiator or .ank, and a flexible connection between said fiting and gage tube.

2. An adjustable gage for automobile radiators comprising a pair of bracket members engageable with the front of the radiator and adjustably and rigidly connected together by a rod, one of said brackets having a gage tube secured thereto and the other of said brackets carrying a connectionlitting adapted to be connected. to the lower portion of the radiator, and a flexible connection between said fitting and gage tube.

3. An adjustable gage tube for automobile radiators, comprising a pair of superposed brackets, a threaded rod adjustably connecting said brackets together, a gage tube secured to the upper bracket and extending upwardly therefrom, a connection-fitting secured to the lower bracket and adapted for connection with the lower portion of the 10 radiator, pipe sections extending from opposing faces of the brackets, and a flexible connection between said pipe sections.

111 testimonv whereof we afiix our signatures.
